Area of a triangle
A
triangle
is a figure formed when three noncollinear points are connected by segments.
Each pair of segments forms an
angle
of the triangle. The vertex of each angle is a
vertex
of the triangle.
The sum of the measures of the angles of a triangle
is 180.
where b is the base and h the height
Find the area of the triangle
Find the area of the triangle when b=4, h=7
